4 Claims.

The invention relates to razors of the type adapted to be used incombination with a magazine injector such as is disclosed in UnitedStates Patent to Rodrigues No. 2,109,017, issued February 22, 1938. Moreparticularly, the invention relates to an improved means whereby the twocomponent parts of the razor head may be separated topermit theinsertion of a blade and may be permitted to approach each other underspring pressure in order to clamp the blade in proper shaving position.

Referring to the drawing,

Fig. 8 is a detailed view of the cam slide and injector nger of themodified form. l

Describing what is shown in the drawing, aA shank I0 mounted in thehandle II terminates in a blade clamping member which includes the' backplate I2 and the overhanging plate I2a and is provided with an eye I3which may be conveniently struck out of it by conventional stampingmethods. The eye serves as a hinge member for a blade platform membercomprising the plate I4 terminating in a blade platform I5, the bladeplatform in turn terminating in a guard I6 and having mounted thereonblade `stops I1 and I'Ia. The plate I4 which serves as a support for theblade platform is also provided with a grooved portion I8 which servesas a cam member for parting the blade clamp I2 and the blade platformI5, as will presently be explained.

Pivotally mounted at 20 on the shank III is a spring latch I9 formed toa bend 2I and it is obvious that as the spring latch is swung on thepivot 20 to the position shown in Figs. 1 and 2, it will yieldingly urgethe blade platform member toward the shank -IIl and likewise the bladeplatform I5 toward the back plate I2. When the spring latch is swungclear of the plate I4, the latter is free to swing forward on its hingedconnection above referred to and free the blade A from the clampingpressure exerted by the blade clamping member and the blade platformmem- 6 ber, it being understood that the relationship between these twomembers is such that, when the head is closed-i. e., when the parts arein the position shown in Figs. 1 and 2, the blade is tightly clamped andthe shoulder 22 drives the 10 blade edge into abutment with the stops IIand I'Ia.

It will be observed that the shank III abruptly* cur-ves rearwardly to aslight extent as indicated by the numeral 23 (see Fig. 3), thus, incoopera- 15 tion with the plate I4, forming a slot 24 between the plateI4 and the shank. In this slot is carried a slide 25 provided with a cam26 which, when the slide is fully in as shown in Fig. 1, registers withthe grooved portion I8, and since in this position it exerts no forcetending to separate the plate I4 .from the `shank I0, the blade A isfirmly pressed against the stops I1 and Ila and the plate '|211 bearsdown firmly on the blade itself. With the parts in this relationship(which is shown in Fig. 2), the slide is not bearing on either the plateI4 or the shank I0, and in fact it is purposely made thin enough so thatthis will not take place when a blade of the proper width is' in shavingposition as shown in Fig'. A2. Obviously, however, if the slide isdriven rearwardly by the insertion of the magazine finger 21 or anyother agency, the cam 26 will force the plate I4 away from the shank I0and likewise the blade platform I5 away from the back plate I2, thus 3fincreasing the fore and aft width of the channel in which the blade iscontained and also its height.

Since the primary purpose is a razor head of improved construction intowhich the blade can be transferred by an injector magazine, We show sucha magazine 29 provided with the aligning nger'2'l already mentioned.'Ihe injector maga-4 zine is essentially similar to the injectormagazine shown in the above-mentioned United States Patent to RodriguesNo. 2,109,017, issued February 22, 1938, and requires no explanationfurther than to say that, when properly lined up with' the razor head byinserting the aligning finger 21 in the slot 24 to its full length andoperating the injector plunger 30, a blade is transferred from themagazine into the blade channel already referred to, any blade alreadyin the blade channel being ejected therefrom by the blade beingtransferred. In this case, however, we 65 tion) that the widening andheightening of the blade channel through the forward swinging of theplate |4 and in opposition to the spring latch' I9 shall be effected bythe slide operating against the plate |4 through the cam 26. In otherwords, as the aligning finger is inserted in the slot, it drives aheadof it the slide 25, which through its cam 26 opens the blade channelpreparatory to the transfer thereto of a blade from the magazine. Afterthe blade has been transferred by a stroke of the plunger 30, thealigning finger 21 of the injector magazine may be withdrawn from theslot, leaving the slide 25 retracted as shown in Fig. 5. FollowingAwithdrawal of the aligning finger, the slide may be restored to theposition shown in Fig. 1 by a simple movement of the finger upon thecompletion of which movement the parts are in the position shown in Fig.2 with the blade A firmly abutting the stops and firmly clamped betweenthe overhanging' plate |2a and the blade platform. Another use to whichthe slide may be put is to produce a slight .separation of the partswithout making use of the injector finger. This is done by simplyoperating it by seizing the thumb piece |60. and] withdrawing the slide.

In the modification shown in Figs. 6, '7, and 8, we have provided aslide 3| similar to the slide 25 except that the slide 3| is brought outnearer to the mouth of the slot 24 and is provided with a hole 32opening to the end of the slide asshown at 33. The aligning finger 34 ofthe injector magazine is similar to the aligning nger 21 except that thealigning finger 34 terminates in a disc 35, extending from the end ofthe finger and connected by a narrow neck 36 to the linger itself. Thehole 32 and the disc A35 form an interlocking couple whereby when it isdesired to transfer a blade, the disk 35 may be inserted in the hole 32,and the slide 3| driven to retracted position. In order to permit accessto the hole 32 in the slide, the plate I4 is cut away as shown at 31.After a blade has been transferred 'to the blade channel, withdrawal ofthe magazine iinger 34 draws the slide with it to the position shown inFig. 6, and since the plate I4 is thereby released, the transferredblade is clamped securely in the blade channel as in the preferredconstruction.

v Itis recognized that the present invention may be embodied in otherconstructions than'those herein specifically illustrated, and thereforeit is desired that the constructions disclosed shall be considered asillustrative and not in a limiting sense.

We claim:

1. A razor comprising two members having yielding connection one withthe other and shaped to form a channel for accommodating a prefer (whichis one of the features oi' the lavan-- blade between them, and apermanently installed slide interposed operatively between them andprovided with a cam adapted when moved to one position lto permit one ofthe members to approach the other and clamp a blade in the channel andwhen moved to another position to cause one of the members to recedefrom the other and thus separate them sumciently to permit of theinsertion of a blade in the channel.

2.
